[Ratt396]

Sorry don't mean to start a new topic for a dum ? But on theses new trucks 2007and on when is a good time to change the spark plugs and wires? And what would b the plug to go with for mine 4.8 cai,super chips programer 3" exhaust. I don't hav any issues but a tps code now and then looking into what I can find that would b a little better than stock before I change the throttle body. just wondering thks
